Key Parameters

Substitute Part Grouping Explanation

Substitution of the MDS001C is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Current Rating: 300mA DC minimum requirement
• Voltage Rating: 30V DC minimum requirement
• Actuator Type: Lever, straight configuration
• Mounting Type: Through-hole compatibility
• Termination Style: PC pin connection
• Switch Function: On-momentary operation
• Mechanical Characteristics: Operating force (50gf) and release force (3.000gf)
• Lifecycle Ratings: Minimum 30,000 electrical and mechanical cycles
• Compliance: RoHS and REACH certification status

The MDS6500AL02PS meets all these criteria while offering active product status and extended operating temperature range, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The MDS6500AL02PS is the direct substitute for the obsolete MDS001C. Both components share identical electrical specifications, mechanical characteristics, and termination requirements. The MDS6500AL02PS provides the additional advantage of active product status, ensuring continued availability and supply chain support. The extended operating temperature range (-25°C to 70°C versus -10°C to 60°C) and updated ROHS3 compliance certification provide enhanced environmental performance and regulatory alignment. For applications operating within the original MDS001C temperature specification, the MDS6500AL02PS operates as a complete functional replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can the MDS6500AL02PS be used as a direct replacement for the MDS001C without PCB modifications?

A: Yes. Both components feature identical through-hole PC pin termination, straight lever actuators, and mechanical mounting interfaces. No PCB layout changes are required.

Q: What is the difference in operating temperature range between these parts?

A: The MDS001C operates from -10°C to 60°C, while the MDS6500AL02PS operates from -25°C to 70°C. The MDS6500AL02PS provides extended low-temperature and high-temperature capability. For applications within the original -10°C to 60°C range, both components perform identically.

Q: Are the electrical specifications identical?

A: Yes. Both components are rated for 300mA DC at 30V with SPDT circuit configuration and on-momentary switch function. Electrical life and mechanical life ratings are both 30,000 cycles.

Q: What is the significance of ROHS3 compliance on the MDS6500AL02PS?

A: ROHS3 represents the current RoHS directive compliance standard. The MDS6500AL02PS meets this updated certification, while the obsolete MDS001C carries the earlier RoHS Compliant designation. Both are lead-free and comply with hazardous substance restrictions.

Q: Is the MDS6500AL02PS available in the same packaging as the MDS001C?

A: The MDS6500AL02PS is supplied in bulk packaging, whereas the MDS001C was supplied with standard packaging. Packaging format does not affect electrical or mechanical compatibility for through-hole applications.

Q: Are the mechanical actuation characteristics identical?

A: Yes. Both components feature 50gf operating force and 3.000gf release force, ensuring identical tactile response and actuation behavior in end-use applications.
